7 Best Unified Inboxes for Vacation Rentals (2026)

If you want Airbnb, Booking.com, Vrbo, WhatsApp, SMS, email and phone calls in one inbox, with AI that replies and can change the booking, Conduit Inbox confirms all seven channels on its own pages. Alfred, Base360, Guesty, Hostaway and SupaHost each confirm six. The table below shows every channel, with a source for every yes.

Which unified inbox tools cover Airbnb, Booking.com, Vrbo, WhatsApp, SMS, email and voice?

I checked seven unified inbox tools for vacation rentals against seven guest channels and two questions about the AI: does it send replies by itself, and can it do anything to the reservation beyond answering? Every "Yes" comes from the vendor's own page, read on 2026-10-24 and linked in that tool's section below. "Not published" means the page did not say, which is different from "no".

How is this list of unified inbox tools organized?

The seven unified inbox tools in this list are grouped by the job they do. Conduit, Alfred and SupaHost are AI layers that sit on top of the PMS you already run, ordered by how many of the seven channels their pages confirm, with ties listed alphabetically. Base360, Guesty, Hospitable and Hostaway are property management systems with a built-in inbox, listed alphabetically. You can also run one from each group, since Conduit connects to Guesty, Hostaway, Lodgify, Streamline, Track and other PMSes (PMS docs). I run Conduit, so read the Conduit section knowing that.

Which AI inbox tools work on top of your PMS?

An AI inbox that works on top of your PMS pulls guest messages from the PMS, the OTAs and your own phone and messaging accounts, then answers them with an AI agent. An AI layer fits operators who want to keep their PMS and add automation, and portfolios that run more than one PMS.

1. Conduit Inbox

Conduit Inbox brings "SMS, WhatsApp, email, calls, social messages, and connected OTA threads into one workspace," and shows booking details, stay history and availability from the connected PMS next to each conversation. The channel docs list email, phone and SMS, a Voice AI number, iMessage, WhatsApp, Instagram, Messenger, LINE and a website widget, plus Airbnb, Booking.com, Vrbo and Expedia.

The agent can also change things in your systems. A PMS connection can expose actions "such as updating a reservation or creating and updating tasks," each switched on one at a time, and the Devices add-on adds access-code management for smart locks. Agents start on copilot, where they draft and a person sends, and you move them to autopilot when the answers hold up.

Cash Flow Street, a 35-property manager, reached 96% automation on Conduit, up from 80% at launch. Across Conduit's 300+ hospitality brands, automation usually lands between 70% and 90%.

Watch-outs: Booking.com and Vrbo messages arrive through your PMS, or, if it does not carry them, through the email address those OTAs notify (OTA channel docs). Expedia is linked one property at a time through Conduit support. The Messaging package, which includes the inbox and voice AI, starts at $18 per unit per month (pricing).

2. Alfred

Alfred describes itself as a "standalone AI messaging platform" that covers "Airbnb, Booking.com, VRBO, WhatsApp, email, SMS" from a single interface, "responding to every message autonomously." It publishes a flat price of "$39.99/month per property." Its page does not publish phone calls or reservation changes.

3. SupaHost

SupaHost covers "Airbnb, Booking.com, WhatsApp, email and your direct-booking inbox," and lets you "choose per-topic whether the AI sends automatically or drafts a reply for your approval." Its pricing page adds SMS to the shared inbox, a dedicated AI phone line on the Scale plan and automatic door codes for one smart lock on Pro. Plans run from Free (€0) to Scale at €15.40 per active property per month. Vrbo is not named; the page says "all OTA messages."

Which property management systems include a unified inbox?

A PMS with a built-in unified inbox keeps messages, calendar and bookings in one login, and its AI works inside that PMS. Base360, Guesty, Hospitable and Hostaway all publish one. All four are listed alphabetically, and the right pick is usually the PMS you already run.

Base360

Base360 is a short-term rental PMS whose inbox takes "Airbnb, Booking.com, WhatsApp, email, SMS and phone calls." When nobody on the team answers a call, "AI picks up and handles the call like an operator," then adds a summary, the recording and a transcript. Each inbox runs on auto-reply, drafts or off. For questions about dates or extending a stay, the AI "checks live availability and rates," and the page states that "AI never creates a task on its own." Pricing is not published.

Guesty

Guesty's Unified Inbox "consolidates messages from Airbnb, Vrbo, Booking.com, email, SMS, and WhatsApp," and Guesty ReplyAI and AI Autopilot "draft or auto-send on-brand replies," while AI Task Creation "turns any guest message into a one-click assignable task." The pricing page includes the inbox on every plan, with Guesty Lite from $9 per listing per month for 1-3 listings.

Hospitable

Hospitable's Unified Inbox handles "Airbnb, Vrbo, Booking.com, Agoda, and direct bookings," and its AI "drafts responses to common questions in your tone - ready to send in one click." A Hospitable guide describes an option for a fully automated AI Inbox, and says its AI "can also fill vacant nights automatically by offering your guests extended stays." WhatsApp, SMS and voice are not published on the inbox page.

Hostaway

Hostaway's inbox covers "Airbnb, Vrbo, Booking.com, Google, email, SMS, and WhatsApp," with two-way SMS and WhatsApp built in, and lets you "choose which messages are sent automatically and which you want to review first." Hostaway AI CoHost answers questions about your live data and "makes the updates in one click," such as listing changes. CoHost is included in the Hostaway subscription; the subscription price is not published on those pages.

Can the AI in a unified inbox change a reservation, or only reply?

All seven unified inbox tools here have AI that replies to guests, and fewer publish that the AI changes anything. Conduit's docs describe PMS actions such as updating a reservation, SupaHost publishes automatic door codes, and Hostaway's AI CoHost applies listing and pricing updates. Guesty turns messages into tasks, Base360 reads live availability and rates, and Hospitable's AI offers extended stays. Alfred's page does not cover reservation actions.

An early check-in request shows why the column matters. Answering it means checking the calendar, asking the cleaner, charging a fee and confirming with the guest. If the AI can only reply, a person still does the other three steps. I walked through that case in guest messaging and operations in one system.

How much does a unified inbox for vacation rentals cost?

Published prices for unified inbox tools for vacation rentals run from free to $39.99 per property per month, and each vendor charges on a different unit. SupaHost runs from €0 to €15.40 per active property per month, Guesty Lite starts at $9 per listing per month, and Alfred lists $39.99 per property. Conduit's Messaging package starts at $18 per unit per month, and its Startup plan covers 0-25 units for $899 a month. Base360, Hospitable and Hostaway did not show a price I could confirm on the pages I read. Check the channel columns before the price, because an inbox that leaves WhatsApp or phone calls outside it moves that work back onto your team.

When does a managed service like Conduit Overwatch fit better than an inbox?

Conduit Overwatch fits operators who want the inbox answered for them, around the clock, without staffing it. Overwatch is a 24/7 virtual operations service where Conduit's AI answers routine guest questions in seconds and trained hospitality operators take over when a situation needs judgment. It covers phone calls, Airbnb, Booking.com, Vrbo, Expedia, direct bookings, SMS, email, WhatsApp, Messenger and Instagram, and the same team handles reviews, turnover coordination and maintenance. Overwatch is priced on request through the pricing page.

How do I choose between a PMS inbox and an AI layer?

Choosing between a PMS inbox and an AI layer comes down to how many systems you run and which channels your guests use. If you run one PMS and most guests write through Airbnb and Booking.com, test the inbox your PMS already includes. If guests also call or use WhatsApp, check those two columns first, since they are the cells most often marked "not published". If you run several PMSes or want the AI to change bookings and dispatch work, an AI layer such as Conduit sits across all of them.
